.SH SYNOPSIS
scalbn, scalbnf \- scale by integer
.SH ANSI_SYNOPSIS
#include <math.h>
.br
double scalbn(double 
.IR x ,
int 
.IR y );
.br
float scalbnf(float 
.IR x ,
int 
.IR y );
.br
.SH TRAD_SYNOPSIS
#include <math.h>
.br
double scalbn(
.IR x ,<[y]>)
.br
double 
.IR x ;
.br
int 
.IR y ;
.br
float scalbnf(
.IR x ,<[y]>)
.br
float 
.IR x ;
.br
int 
.IR y ;

.SH DESCRIPTION
.BR scalbn 
and 
.BR scalbnf 
scale 
.IR x 
by 
.IR n ,
returning 
.IR x 
times
2 to the power 
.IR n .
The result is computed by manipulating the
exponent, rather than by actually performing an exponentiation or
multiplication.
.SH RETURNS
.IR x 
times 2 to the power 
.IR n .
.SH PORTABILITY
Neither 
.BR scalbn 
nor 
.BR scalbnf 
is required by ANSI C or by the System V
Interface Definition (Issue 2).
